I-Jet iyindlela ekhulu yokusetshenziswa kwesakhiwo esikhulu se-Boan abrasive water jet coal seam cutter pressure relief device, okuyinto isicelo esinikezwe kanye nokuthuthukiswa okwenzekile okwenzelwe ngokwemvelo ekwenzeni ukuphuma kweslagi ekupheleni kwezinkinga zokudrila ezindaweni zezimboni, kanye nokwenza ukuguqula kwamandla angaphakathi nezitha zika-jet ngokusetshenziswa kwesethiwekhi esihambisana, okwenza kube kuhambisana nezidingo ezithile zezindawo. Isakhiwo sisekelwe ngokwezinzima, isisindo esincane, ukupheka okulula kanye nokwenza ukwenza okuncane, kanye nokwenza okunqamulekile kwezinto ezithintekayo.
Ngesikhathi sokwenza umsebenzi wokwakha, i-valve yokuguqula ekwenzeni ukuphuma kwamanzi okwenzekile kwi-injector kungathuthukisa ukudrila kwamanzi okwenzekile okwenzekile kanye nokwamandla okwamanzi okwenzekile; isimo esinikezwe kwi-switching spool kuyi 3~5MPa, kanye nokukhula kwamanzi okwenzekile okwamanzi okwamanzi kuyi ≥700mm; irange ethintekayo ye-f=0.2~1.5 kungathuthukisa ukukhula kwamanzi; i-injector iyetha isistimu yokwenza ukuthinta okuprecise, kanye nokuthi inezindlela eziningi zokuphuma kwamanzi kwiqoqo, kanye nokwenza ukuguqula kwamanzi kwezinkinga kuyi 150~160L/min, okungathintwa ngokwesidingo. Okuthintekile ngokwesidingo, kunezinto yokwenza okuhlanganisiwe kwezokudrila nokukhomba, okwenza kube kuhambisana nokwenza okuhamba okubili kwesikhala.
